want to build a 3 point stump saw

If the slip clutch hasn't been loosened, then slipped, then tightened to specs within the last year......., then it probably has fused together and needs to be addressed. i.e. loosened up, made to slip 4 or 5 times, and then adjusted equally on all the bolts so that it just slips. ;)

It should slip before the gear boxes fail.

Our slip clutch is a Walterscheid I think. The man that sold the mower to me, said he thought that slip clutch left a little to be desired.

Instructions say to tighten the nuts up on the bolts & then slip it. Then back off to reset or engage. The bolts have been flattened past the nuts, to keep them from coming off.
We did tighten, then slip the clutch, then just backed nuts back out maybe 1/3rd way, thinking we are not applying full pressure. It then acted as if it didn't want to slip.

Must be a point there where the clutch will slip. Here are the apparent instructions, implying that the bolts are to be backed out against the peened over bolt end that you mentioned. Good luck......

Found the Walterscheid clutch here:  (not certain this is your hog)

Beenthere, we did follow those instructions. It doesn't seem to have intermediate powering adjustment. On our other slip clutches, after removing spring tension & slipping the clutch, we are able to tighten, until we get the desired amount of power before it slips. Normally, I will see it slip on a quick start and know it is working.

This one just doesn't seem to be as versatile.

I guess a different clutch or maybe new plates are in order. Possibly torn up plates inside too. Would have to take it apart to find that out. Good luck with it.

Farmboy,
Nice work, and thanks for taking the time to figure out the photo posting thing, I know it can be difficult for the first few tries, it gets easier though! 

I've often thought of cutting out a portion of my heavy duty rotary cutter, just like you did where your saw is exposed.  It would make the rotary cutter more like a miniaturized "Brown Tree Cutter"

I would probably have to beef up the outside edges though as I'm sure removing all that steel would weaken it a bit.
